I was playing once I got it all wired up and noticed that I'm only getting signal from the "Right" amp sometimes. I narrowed it down to the M9. When I use an effect like Bias Trem, Chorus, Octo, I get both amps, but if I choose Analog Delay, I only get the "Left" amp.
So, I bypassed the M9 in my "right" signal and ran it from the TF to the RV5, and that got me signal all the time, both amps.
Anyone have any idea as to what is going on with the M9? Is it a software thing, a hardware thing, or some setting I haven't learned about yet? Pretty frustrating as I thought it would be pretty good for a lot of cool 3D sounds.
